coupler are visibly aligned (no gap can be seen between coupling faces when butted
together). Adjust engine height if necessary to obtain proper alignment. DO NOT use
mount adjustments to adjust engine position at this time.
IMPORTANT: Engine bed must position engine so that a minimum of 1/4 in. (6 mm)
